CURTAIN-SUPPORT.

Specification of Letters Patent.

Patented J une 19, 1917.

Application filed September 7, 1916. Serial No. 118,824.

To all whom it may concern.

Be it known that I, AUGUSTA E. ROBERT, a citizen of the United States, residing at Oakland, in the county of Alameda, State of California, have invented new and useful CurtainSupport, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates, to a curtain fixture, the object of which is to provide convenient means for preventing the curtain from being soiled when the window is opened, either at the top or the bottom.

It will be understood by housekeepers that lace curtains are soiled mostly by the incoming air either at the top or at the bottom of the window when the sash is left open,the curtain acting as a filter in collecting the dirt and soot that may be in the air. In the present invention means is provided whereby the lace curtain may be raised when the lower sash is raised, or lowered when the upper sash is lowered, thereby preventing the incoming air from passing through the curtain, and keeping it clean.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be many modifications thereof.

Figure 1 is a front elevation of a window and window frame having this invention applied thereto,

Fig. 2 is a vertical sectional view of one of the curtain rod supports looking in the plane of thewindow frame,

Fig. 3 is a sectional view of the support shown at the right of Fig. 1, the plane of section being parallel to the window frame,

Fig. 4 is an enlarged section showing the lower end of one of the supports, and

Fig. 5 is a horizontal sectional view of one of the curtain supports and a portion of one of the curtain rods.

The numeral 1 indicates the window frame, 2 the upper sash and 3 the lower sash. Attached to the window frame on opposite sides of the window are two tube like members 4 and 5. Each member 4 and 5 is provided with a long rack bar 6, which receives and is in mesh with small gear wheels 7 and 8 on opposite ends of the shaft 9.

The shaft is of such length as is necessary and it is provided with a sprocket gear 10 at end one thereof. The shaft 9 is journaled in two slides 11 and 12 at the ends, said slides holding the curtain.

The slides 11 and 12 are movable in slots in the side of the members 5 and 6 and an extension head 13 prevents the displacement of the slides when the curtain is raised or lowered.

' At the top of the member 4 there is a sprocket wheel 14 on a shaft 15 over which an endless chain 16 passes. One run of the chain is also in contact with the sprocket wheel 10 whereby the shaft 9 may be rotated and the curtain rod raised or lowered as der sired. At the lower end of the member 4 there is a pin 17 which enables the chain. to be stopped at any desired adjustment of the curtain rod.

The slides 11 and 12 are each provided J;

with a projecting tube as shown at 18, each of which has a short forwardly projecting rod 19 for the support of narrow corner drapes. The main curtain rod is shown at 20 and is tubular, extending over the projecting ends of the slides thereby enabling the supports to be used with windows of any desired width.

The operation of the support is as follows: Assuming the curtains to be placed in position on their rods the curtain rod may be adjusted so the end of the curtain will just reach the bottom of the window. If the window is opened at the bottom the chain may be operated to raise the curtain about a foot by pulling down on the outer run of the chain. When so lifted the air coming in below the sash will pass into the room without passing through the curtain and thereby preventing the curtain from accumulating dirt. When adjusted to the desired height,

the curtain is fixed in that adjustment by having one of the links of the chain hooked under the pin 17.

If the upper sash is to be lowered the curtain rod may be lowered thereby preventing the top of the curtain from accumulating the dirt in the air coming in at the top of the window.

It will be understood that while each fixture has a rack bar that only one is provided with a sprocket wheel and chain, the shaft 9 extending from one fixture to the other inside the curtain rod and having a gear at each end.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, is as follows, express reservation being made of permissible modifications:

1. In a window curtain support the combination of a pair of slotted tubular members; a rack bar rigid with each member; means securing saidmembers midway of their length to the window frame whereby said members are made to project above said frame; a shaft extending between said members through the slots thereof, and provided with a pinion on each end engaging said rack bars; a pair of guide members located inside said tubular members through which said shaft passes, and having tubular extensions movable'up and down in said slots; a main curtain rod mounted on said extensions; a

sprocket wheel mounted on said shaft; a

sprocket chain passing over said sprocket wheel adapted to raise and lower said guides,

' and main curtain rod; and means supporting said sprocket chain at the upper end of said tubular guide, substantially as described.

2. In a window curtain support the combination of a pair of tubular members pro vided with slots; a rack bar rigid with each member; means to secure said members to the frame of the Window; a shaft extending between said members through the slots thereof and provided with a pinion-on each end engaging said rack bars; a pair of guide members carried by said shaft in which the latter is journaled and havingtubular extensions movable up and down in said slots; a main curtain rod mountedwon said extensions; a sprocket wheel mounted on said shaft in one of said tubular members; a sprocket chain passing over said sprocket wheel adapted to raise and: lower said guides and main curtain rod; means supporting said sprocket chain at the upper end of said tubular guide; and means to se cure said chain in any desired position, substantially as described.

In testimony whereof I have hereunto set my hand this 1 day of September A. D. 1916.

AUGUSTA E. ROBERT.
